Abstract

An information monitoring and updating method and system for a transport stream is provided. First, a transport stream is received. The transport stream includes a program specific information (PSI) table, and the PSI table is divided into a plurality of sections. Next, by setting a first filtering parameter of a monitor-section filter, the header of each section of the PSI table is filtered out and is then checked whether to be a latest version or not. When all the section headers of the PSI table are of the latest version, each section of the PSI table is filtered by setting a second filtering parameter of a table-section filter.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority benefit of Taiwan application serial no. 96103374, filed on Jan. 30, 2007. All disclosure of the Taiwan application is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a transport stream, more particularly to an information monitoring and updating method and system for a transport stream.

[0004] 2. Description of Related Art

[0005] The development of digital TV industry brings along tremendous demands to multimedia home platform (MHP). Accordingly, various digital TV standard organizations have established their own middleware standards so that digital TV receivers conforming to these standards can perform diverse multimedia interactions, information applications, and services, such as electric program guide, real-time stock information, and TV shopping etc.

[0006] However, different countries or regions have different middleware...

Embodiment Construction

[0035]For the convenience of description, it is assumed that the present invention is applied to a digital TV receiver platform for monitoring and updating the information of a MPEG-2 transport stream. However, the present invention is not limited thereto; instead, the present invention may also be applied to other fields, such as a BD-J interactive CD player platform.

[0036]The present invention provides an information monitoring method of a transport stream. First, a transport stream is received, wherein the transport stream includes at least one program specific information (PSI) table, and the PSI table is divided into a plurality of sections. Next, the header of each section of the PSI table is filtered out by setting a filtering parameter of a monitor-section filter, and information monitoring is then carried out by using these section headers.

[0037]The present invention further provides an information updating method of a transport stream. First, a transport stream is received...
